Document Summary

Describe the anatomical location and functioning of the mitral valve. Between the left atria and the left ventricle. Once we have ventricular pressure builds up it functions to prevent back flow of blood from the ventricles to the atria. The chordae tendineae are connected to papillary muscles to close this valve. Rheumatic fever is the inflammation of certain tissues in the body. Not specifically a fever, its an inflammation of specific tissues. The antibodies trying to fight this fever are attacking proteins found in the heart due to similarities between the proteins they should actually be fighting. This causes scarring of tissues, causing dysfunction of the tissues or valves. Inflammation of tissue in the heart region, could be in the valve, causing the valve not to close properly. In typical individuals you hear the lubdub (due to valves opening and closing) In this individual you hear a heart murmur, indicating that something isn"t working as smoothly as it should be.
